Without question, HDR, in fact I've seen several as early as 6 am and there were some nice ones in the group.
Surprisingly, I think SL has more attractive more cooperative non hustlers noonish through 4 or 5 when it starts to fill up. Usually it's a smaller crowd, but it appears a greater choice of sweeter more fun non rush girls, so if you don't find anything to your liking early at HDR, scoot up to SL for lunch.
On the other hand,

Monica's opens at 9 am and they have a plethora of hotties, all sweet and cooperative, clean rooms and private showers. 16k for 30 min, 20k for 1 hour, most girls will request 10k for everything within reason, dfk, gfe, 69, bbbj all available. One hour everything you want (unless you're especially weird), propina included, $54 USD. If you have a bad back, get a taxi there and back, it's not far.
